ACETYLENE-GAS BURNER.

SPEGIFIGATION formingpart of Letters Patent N 0. 652,141, dated June 19, 1900. Application filed December 30, 1896; Serial No. 617,469. o model.)

To all whom, it may concern.-

Be it known that I, KARL HEINRICH RAUPP, a subject of the German Emperor, residing at Mentz, Hesse, Empire of Germany, have invented certain new and useful Improvementsin Acetylene-Gas Burners, of which the following is a specification.

The object of the present invention consists in a burner for acetylene gas, which is characterized thereby that it always burns soot-free.

A tube b, of material not attacked byacetylene, such as aluminium, is screwed into the tubular conduit (not shown) by a screw a, and has its upper portion bent in the form of a circular arch, which is arranged in a vertical plane, and is perforated along its top with a plurality of small holes, the directions of which diverge by reason of the circular bend of the tube. The flames issuing from the outer wall of the bent part, by means of the small holes provided therein, are directed radially from the centerA of the circular are 0. Thus the distance between the flame points d is greater than that between the bases 6 of the flames, so that such an abun dant supply of air is effected that the flames, even under fluctuation of pressure, burn free from soot.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

A burner for acetylene gas, consisting of a tube having its upper portion bent into the form of a circular are arranged in a vertical plane, and having a plurality of small holes along its top, the direction of such holes di= verging by reason of the circular bend of the tube, substantially as and for the purpose set forth.

. In witness whereof I hereunto set my hand in presence of two witnesses.
